HOWARD J. TREGANZA, OF NEW YORK, N. Y., ASSIGNOR TO THE ANSONIA CLOCK COMPANY, OF NEW YORK, N. Y., A CORPORATION OF CONNECTICUT.

ALARM-CLOCK.

To all 1071 am it may concern:

Be it known that I, HOWARD J. TREGANZA, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and useful Improvement in Alarm-Clocks, of which the following is a specification.

My invention relates to an improvement in alarm clocks with the object in view of providing an arrangement of the parts whereby the dial, movement, bell and back may be removed intact for the adjustment of the movement, etc.

Another object is to provide simple and effective means of securing the back of the clock to the casing, said back having secured to it the dial, movement and bell.

A practical embodiment of my invention is represented in the accompanying drawings, in which,

Figure 1 represents a plan view of a clock casing of my construction with a part of the casing broken away to show certain parts more clearly, Fig. 2 represents an inverted plan view of the same, Fig. 3 represents a side elevation of the same, Fig. 1

represents a transverse central section taken from front to rear, the casing and fastening devices shown in dotted outline removed from the back, and Fig. 5 represents a detail view showing the means of attaching the rear foot.

The cylindrical casing is denoted by 1, and is provided with an inwardly turned annular flange 2 for retaining the glass 3. The side walls 4 of the back 5 are provided with a turned back flange 6 forming an annular recess between said side Walls and flange. A support 7 is struck out from the back 5, to which the bell 8 is secured by screws 9. The clock movement 10 is secured to the back 5 by means of its posts 11, the rear ends of which project through the back and are provided with nuts 12 as shown in Fig. 4. An opening 13 is pro- .vided in the side walls 4 of the back 5 for the passage of the hammer, (not shown,) to the bell 8. A dial 14 is fixed in position to the clock movement 10 by means of lugs 15 projecting inwardly from the dial. A rearwardly extending foot 16 is secured by rivets 17 to the turned back flange 6, through which flange and foot I provide one means of locking the flange and casing in position, the said locking means consisting Specification of Letters Patent.

of a screw 18 which passes through a hole 19 at the bottom of the casing 1 and has a screw threaded engagement with the flange and foot. I also provide another means for locking the casing to the back at the top of the clock, which means consists of a lug 22 secured to the back 5 between the side walls -1- and flange 6 and projecting forwardly therefrom and a screw 23 which passes through the casing 1 and has a screw threaded engagement with the lug A dial mat 2% is interposed between the glass 3 and the dial 14. A handle 25 is secured at the top of the casing 1 in any well known or approved manner. Two legs 26 are also secured to the bottom of the casing 1, upon which legs and the rear foot 16 the clock stands. The particular construction of the back affords the bell which extends forwardly into the recess between the side walls at and flange 6 ample protection as well as concealing the means of attaching the movement to the back.

It will be seen when assembling that the back carries the movement, dial, rear foot and the locking lug and is inserted within the casing as a whole, which is locked in position in the casing, only by the screws 18 and 23. The dial 14- when in position will tend to force the dial mat 24 and glass 3 to its seat on the flange 2. To remove the movement from the casing for adjustment or other purposes it is only necessary to remove the screws 18 and 28, when the back carrying the movement may be withdrawn from the casing.

It will be understood that while I have shown the screw 23 capable of performing another function, not shown or described in this application, I may insert a common machine screw in place thereof for securing the casing and back together.

\Vhile I have not shown certain of the mechanism contained in a clock case and movement it will be understood that the back and bell are provided with such openings as may be necessary for the projection through the said back and bell of the usual alarm switches, setting and regulating arbors, winding keys, etc., as may be required to complete the clock, all of which will be carried or removed with the back.

It is evident that slight changes might be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not Wish to limit" myself strictly to the structure herein set forth, but

What I claiinisz 1. In a clock, a casing, a back having integrally formed side Walls and a rearwardly extended peripheral flange for snugly fitting Within the casing and a rearWa-rdly extended foot fixed to said flange for supporting and reinforcing the flange and casing.

2. In a clock, a casing, a back having integrally formed side Walls and a rearwardly extended peripheral flange for snugly fitting Within the casing, a rearwardly extended foot fixed to said flange for supporting and reinforcing the flange and casing, and a removable fastening device adapted to engage said casing, flange and foot.

In testimony that I claim the foregoing as my invention, 1 have signed my name in presence of two Witnesses, this 10th day of November, 1913.
